CARRIER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 332,961, dated December22, 1885.

Application led November 1B, 185. Serial .No.183.22l. (No model.)

To all whom i6 may concern:

Be it known that I, HERvEY SMITH, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in` Carrier Apparatus; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in t-heart to which it appertains to make and use the same.

This invention relates to carrier devicessuch as are used in stores andother like placesin which the track is suspended and the car consists ofa trolley running on the track and a receptacle suspended below thetrack from the trolley; and it consists in certainimprovements in theconstruction thereof, as will loe hereinafter fully described, andpointed out in the claim.

In three companion applications I have shown variously-constructedtracks and cars adapted thereto, similar to what I now show, and in saidapplications I stated that certain features there illustrated would befully eX- plained and properly claimed in this application.

The leading object of this invention is to construct the cars and thetrack so the car can not swing or sway while running on the track nor bethrown from the track.

In Letters Patent No. 326,928, issued to my assignee on September 22,1885, I show a bartrack with a car-trolley having` two sets of groovedor double-flanged wheels, which embrace both the upper and the lowerside of the track. In the construction there shown the cnr Will swing orsway unless the flanges fit so closely to the track as to impede thecar, and unless the flanges are very long or t very closely to the trackthe car may loe derailed.

I have found by actual experience that in order to prevent possiblederailment and swaying or swinging of a car adapted to run on a singleelevated bar-track, the following features of construction areessential: The track must be supported wholly from one of its verticalsides, leaving the three other faces unobstructed; the track must have aWide upper and lower bearing-face, one of which, at least, must beribbed, grooved, or otherwise adapted to engage with flanges onthe-wheel or trolley-frame to keep the car from running off the track;the wheels of the trolley must have a wide tread, so as to bear upon thetrack near its edges; the trolley-frame must have a lateral extensionunder the track, on which may be journaled a friction-wheel, as shown inthe drawings, to operate against the lower face ot' the track, toprevent the car being swayed or lifted up off the track. A trolley thusconstructed will embrace the three unobstructed sides of the track.

I have in the accompanying drawingsshown a variety of track-forms andoars thereon, each of which embodies the essentials of construction Ihave above set forth.

In each figure the track is in vertical transverse section, and. ismarked A. The car is in rear elevation, and its trolley is marked B,with its frame marked b, and its traveling wheels b. The friction-rolleron the `lateral projection from the frame under the track is marked b2.The said lateral projection, when not provided with a roller, as in Fig.4., is marked b3,- and the receptacle which is suspended from thetrolley is marked B. The support of the track is marked A.

The various constructions are as follows:

Figure l shows a track with a rib on both its upper and lower faces anddoubled-Banged wheels. Fig. 2 shows a track ribbed on top and smooth onthe bottom and a car having double-hanged traveling wheels andsmoothfaced friction-rollers below the track. Fig. 3 shows a trackhaving a central groove on both its upper and lower faces anda carhaving centrally-hanged wheels. Fig. 4 shows a track with a centralgroove in its upper face audits lower face smooth and acar havingcentrallyflanged traveling wheels and no friction-roller below thetrack, but thelateral projection lies so close to the track that the carcannot be swung nor lifted up. Fig. 5 shows a track havinga smooth upperface and a grooved lower face and a car with smooth traveling Wheels andcentrally-anged friction-rollers. Fig. 6 shows a track with a centralrib on its upper face and a central groove in its lower face and a carhaving double-flanged traveling wheels and centrally-flangedfriction-roller. Fig. 7 sho/ws a construction the reverse of thatshownin Fig. 6. Fig. 8 shows a track With a smooth upper face and acentrallyribbed lower face and a car having smooth- IOO faced travelingwh eels and double-hanged friction-roller. Fig. 9 shows a constructionlike Fig. 4, except the groove inthe track and the flange on the wheelare wider, and there is a friction-roller below the track. Fig. 10 showsa track havingV ribs on its edges both above and below and acar withsmooth wheels.

It will be observed that wherever the traveling wheels aredouble-flanged they tread on the flanges at the edges of the track-face,and that wherever the traveling wheels are ceutrally flanged they treadon the faces at the side of the iiange and ou the edges ofthe track, andwhere the traveling wheels are smooth or flat-faced the5T are wide andbear on the edges ofthe track, except in Fig. l0, and in thatconstruction the tread-faces of the track and the wheels will be so wideas to effectually prevent swaying.

I shall not here claim as new any of the track-forms shown.

I am aware that railway-tracks on which the car or traveler is whollyabove the track have been made with central ribs and with centralgrooves, and I therefore do not desire to be understood as claiming suchformation of track as new.

What I claim as new is- In a carrier apparatus, the combination, with atrack which is supported from one of its vertical sides, leaving itsthree other sides unobstructed, andis provided with wide upper and lowerfaces, one of which is adapted, as set forth, to receive a langed wheel,of a cartrolley which embraces the three unobstructed sides of saidtrack, bears with its wheels on the edges of the track-face and operatesagainst both the upper and lower faces of the track, substantially asand for the pu rposes set forth.

In testimony whereof I afx my signature in presence of two witnesses.

H ERVEY SMITH.
